ROLLER JEWEL-SETTER.

Application filed January 31,

To all whom it may concern:

Be it known that I, JAMES E. Fonn, a citizen of the United States, residing at Hydro, in the county of Gaddo, State of Oklahoma, have invented certain new and useful Improvements in Roller Jewel-Setters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in jewelers tools, and particularly to a device used in watch repairing.

The principal object is to provide a simple device for holding the balance pinion to facilitate the setting of the roller jewel.

Other objects and advantages will be apparent from the following description and with particular reference to the accompanying drawings.

In the drawings: Figure 1 is an elevation of the device made in accordance with my invention, showing the balance pinion held therein, Fig. 2 is a plan view, Fig. 3 is a vertical section on the line 3 3 of Fig. 2, slightly enlarged, Fig. 4 is an edge elevation, Fig. 5 is an end view of the standards, the balance wheel being removed and the pivoted clamp being held back, and Fig. 6 is a vertical section on the line 6-6 of Fig. 2.

Referring particularly to the accompanying drawings, 10 represents an elongated block of metal, which has secured to one end the laterally extending blade 11, which is preferably of thin brass or copper, and is adapted to be held over the flame of a lamp, as is usual, and well known in the art. Formed in the end of the block 10, to one side of the center is a bore 12, this bore being adapted to receive the shaft 13 of the balan-ce pinion 14, the jewel table 15, of the pinion resting on the end face of the block 10. Formed in the side, at the end of the block and communicating with the bore 12 is a slot 16, in which the jewel 17 is received after being inserted through the opening 18 of the table 15. Formed transversely through the block 10 is the opening 18 and pivotally mounted within this opening are Specification of Letters Patent.

the ears 19 and 20 respectively, of the clamps 21 and 22. The former of these clamps has an inwardly bent upper end 23, the terminal portion being slightly reduced as indicated at 24, and the said end 23 being adapted to engage over the upper face of the table 15, between the table and the pinion 14: to hold the said table tightly against the end face of the block 10. The upper end of the clamp 22 has a blade 25 which enters the slot 16 to engage against the ewel 17 after th same has been inserted in the opening in the table 15. These clamps 21 and 22 are held by means of the leaf springs 26, which are secured to the block 10.

Secured at one end to one side of the block 10 is a bowed spring 27 the opposite end of which is forked as indicated at 28 to register with the transverse opening 29 formed through the block, a suitable clamping screw 30 passing through the middle portion of the spring and a threaded opening in the block. This spring 27 is for the purpose of holding the second hand while broaching the same or setting a pin therein. The lower end of the block 10 is provided with a handle 31.

What is claimed is:

A roller jewel setter comprising an elongated block having an opening in the end for the reception of the shaft of the balance pinion, a pivoted spring-pressed clamp on one side of the block, for engagement with the top of the table of the balance pinion to hold the table against the end of the block, said block having an opening to receive the roller jewel, said opening being formed in one side of the block and communicating with the first named opening, and a pivoted spring-pressed clamp on the other side of the block arranged for passage through the second named opening and engagement against the roller jewel.

In testimony whereof, I affix my signature, in the presence of two witnesses.
